It’s a complex wall at this point, the mash up of bits and pieces on the wall of the old Laundromat on Library Lane, which is pegged to come down in the coming year to be replaced by a sparkling new community-oriented Woodstock Library Annex. There’s tattering remnants of what look like old posters and other historical artifacts, until close inspection shows they’re all a spoof, albeit without any bad intent. Plus a growing number of large-scale doodlings, colorful additions, art posters and found materials that lend added beauty to what’s been morphing for a year, with considerable new activity in recent weeks.
